Download link #1CTS has undermined the priceless trust of its customers twice. Firstly, when the UK real estate market was paralyzed through their fault. And secondly, when they failed negotiations to keep their clients' data safe. Their disregard attitude to cyber security, as well as infinite greed, led to this situation. Initially, we had access just to one client regular VM. Terrible security vulnerabilities and network misconfigurations allowed us to gain access to the entire network in a few moments. How could they provide "Cyber Protection Shaped for Law"? On their website CTS states: Every minute and every decision matters and maximising reputation and minimising risk informs every decision made. If your goal is save your data and reputation, and minimize risks, the best decision will be to avoid the services of this company and switch to another MSP. They do not deserve to provide their services to the legal industry and should stay away from this business. The confidential data from 2 law firms is already being disclosed. What will happen next? We'll see..

cactus

According to ransomware.live, The CACTUS ransomware is said to have emerged around March 2023. The group became known for exploiting vulnerabilities to gain initial access and maintain a presence within the organization's infrastructure. There is little known information about the ransomware group, except that it emerged on the mentioned date and, following encryption, a text file named 'cAcTuS.readme.txt' would be created. Additionally, encrypted files were altered to the '.cts1' extension, and data exfiltration and victim extortion were conducted through the use of the service known as Tox.
